Here are some easy steps to help you troubleshoot md5 for win32.

Open a Windows command prompt. Make Concept Fast: Hit Windows R, Classification cmd and hit Enter! ! !Go to the folder containing your file whose MD5 checksum you want to check and verify.Enter certutil -hashfile MD5.Hit Enter.Compare the received checksum with the expected one.

The attached example shows the use of CryptoAPI to determine the MD5 hash within a file. This example is based on calculating the content associated with a specific file over time.

Download the latest version of WinMD5Free.Unzip the downloaded zip file and run WinMD5.exe.Click the Browse button, run and select the file you want to view.After selecting the file, the plan will show you the MD5 checksum.
